What are the best combat strategies for the mission "American Venom"?

The mission ''American Venom'' in Red Dead Redemption 2 is the final story mission and one of the most intense combat sequences in the game. It requires a combination of strategic planning, effective weapon use, and quick reflexes. The mission takes place on Mount Hagen, where you confront Micah Bell and his gang. To succeed, you need to prepare your weapons, manage your health, and adapt to the dynamic combat scenarios.\n\nFirst, ensure you have the right weapons and supplies before starting the mission. Equip a powerful rifle like the Bolt Action Rifle or Carcano Rifle for long-range engagements, and a reliable sidearm such as the Schofield Revolver or Mauser Pistol for close combat. Stock up on health tonics, potent snake oil for Dead Eye, and plenty of ammunition. These items are critical for surviving the prolonged firefight and dealing with Micah''s gang.\n\nAt the start of the mission, you''ll face waves of enemies as you ascend Mount Hagen. Use cover effectively to avoid taking unnecessary damage. The terrain is rocky and uneven, so position yourself behind large boulders or trees to shield yourself from enemy fire. Peek out to take precise shots, and use Dead Eye to target multiple enemies quickly. Dead Eye is especially useful for thinning out groups of enemies before they overwhelm you.\n\nAs you progress, you''ll encounter enemies with shotguns and rifles. Prioritize these targets first, as they can deal significant damage. Use your rifle to pick them off from a distance before they get too close. If enemies flank you, switch to your sidearm or shotgun for close-quarters combat. The Pump-Action Shotgun is particularly effective for clearing out enemies who get too close.\n\nWhen you reach the cabin at the top of the mountain, the fight becomes even more intense. Micah''s gang will use the cabin''s windows and doors to fire at you. Use the environment to your advantage by staying mobile and avoiding predictable patterns. Toss dynamite or Molotov cocktails into the cabin to flush out enemies or deal area-of-effect damage. Be cautious, as enemies will also throw explosives at you.\n\nOnce you breach the cabin, you''ll face Micah in a one-on-one duel. This is a test of your Dead Eye skills. Activate Dead Eye as soon as the duel begins and target Micah''s weapon hand or head to disarm or kill him quickly. If you miss, stay calm and keep moving to avoid his shots. Use health tonics if your health drops too low.\n\nFinally, after the duel, you''ll have a choice to make regarding Micah''s fate. This is a narrative decision, so choose based on your character''s moral alignment. Regardless of your choice, the mission concludes with a cinematic ending that ties up the story.\n\nPractical tips for this mission include practicing your Dead Eye accuracy in earlier missions, as it will be crucial during the duel. Additionally, always keep an eye on your health and Dead Eye meters, and replenish them as needed. Finally, stay patient and methodical during the firefight to avoid being overwhelmed by the sheer number of enemies.
